Pulse bag dust collector | PPC type air box pulse dust collector

Type air box pulse bag dust collector
The filtration area is from 3/to/, and the processing air volume is from 3/to/. It is widely used in building materials, cement, metallurgy, machinery, chemical industry and refractory materials industries. It is especially suitable for crushing, packaging, etc. in cement plants. Dust collection systems (or dust removal systems) such as silo roofs, clinker coolers and various mills can also be applied to coal mill dust collection, but fire and explosion prevention measures must be added. The structure of the dust collector must also be changed accordingly. It can also be applied to coal mill dust collection For dust collection of gas with extremely high dust concentration, such as the grinding system with a powder separator, the dust concentration of the gas is as high as /3 (standard) or above, and there is no need to set up a cyclone dust collector for pre-dust collection.
Air box pulse
Bag dust collector
The body is divided into several box areas. Each box has one filter bag and a cylinder-driven poppet valve on the side outlet pipe of each box. When the dust collector After filtering the dust-containing gas for a certain period of time (or the resistance reaches the preset value), the dust cleaning controller will send a signal. The lift valve of the first chamber will begin to close and cut off the filtered air flow, and then the pulse valve of the chamber will open to a level greater than .The compressed air rushes into the clean air chamber to clear the dust on the filter bag. When this action is completed, the poppet valve reopens, allowing the chamber to perform filtering work again, and complete all dust cleaning actions according to the above procedures one by one
The air box pulse bag dust collector uses separate chambers for dust cleaning. When cleaning, the boxes are isolated one by one and carried out in turns. The pulse and dust cleaning cycles of each chamber are automatically and continuously carried out by the dust cleaning program controller according to the preset program. , thereby ensuring the effect of compressed air cleaning. The entire box design adopts an inlet and outlet main pipe structure, and the ash hopper can be extended under the inlet main pipe, so that the incoming dust-containing flue gas can directly enter the expanded ash hopper to achieve the predetermined level. The effect of dust removal. Therefore, the type air box pulse bag dust collector can not only handle dust-containing gases with general concentrations, but also can handle high-concentration dust gases
Characteristics of type air box pulse bag dust collector
, this dust collector The dust collector adopts pulse jet dust cleaning technology with air stop in separate chambers, which overcomes the shortcomings of conventional pulse bag dust collectors and backflush dust collectors in separate chambers. It has strong dust cleaning ability, high dust removal efficiency, low emission concentration, small air leakage rate, low energy consumption, and steel It consumes less, occupies less area, operates stably and reliably, and has good economic benefits
. Due to the use of divided-chamber air-stop pulse jet dust cleaning, complete dust cleaning can be achieved with just one blow, so the dust cleaning cycle is extended and reduces the cost. The energy consumption of dust cleaning is reduced, and the compressed air consumption can be greatly reduced. At the same time, the fatigue degree of the dust filter bag and pulse valve is also reduced accordingly, thereby doubling the life of the filter bag and valve plate
. Bag maintenance and replacement can be The system fan is not stopped and the system is operated in different rooms under normal operating conditions. The filter bag mouth adopts an elastic expansion ring, which has good sealing performance and is strong and reliable. The filter bag keel adopts a polygonal shape, which reduces the friction between the bag and the cage bone and extends the length of the dust removal bag. The life of the bag is long and it is easy to remove the bag
. The upper bag extraction method is adopted. After the skeleton is pulled out when changing the bag, the dirty bag is put into the ash hopper at the bottom of the box and taken out from the manhole, which improves the bag changing operating conditions
The box body adopts air-tight design with good sealing performance. The inspection door is made of excellent sealing material. Kerosene is used to detect leaks during the production process. The air leakage rate is extremely low
The inlet and outlet air ducts are compactly arranged and the air flow resistance is small.
